PASSAIC —The New Jersey Policemen's Benevolent Association is offering $20,000 reward for information in connection to the brutal beating of a police officer last month outside a club in Passaic.

Just before 3 a.m. on Nov. 17, a plain clothes police officer was interviewing a witness to a disturbance outside the Zarco Lounge on Main Street. Police said three men attacked the officer knocking him unconscious.

The sergeant was rushed to St. Joseph's hospital where he was treated for a broken jaw, broken nose, and a concussion. His jaw is now wired shut, police said.

“The officer was doing his job when he was beaten unconscious and left with a concussion, broken jaw, and broken nose," PBA president Anthony Weiners said in a statement. "There were numerous people in the area when the attack happened and we need them to come forward to capture the suspects responsible. It is my hope by posting this reward that we will increase the motivation for witnesses to come forward."

The PBA, based in Middlesex County, administers the NJ COP SHOT program which offers rewards for information on crimes against police.
